Add Klipsch finesse and toughness to your workouts "Sweat-proof and super-durable." That's how Vlad Grodzinskiy, head of Klipsch's headphone division, described the T5 Sport Earphones . Those happen to be two key attributes when it comes to workout headphones. Klipsch has the other important stuff covered, too ? like sound, fit, and comfort. Music plays wirelessly from your phone via Bluetooth. These headphones are part of Klipsch's "True" series lineup, so they include a state-of-the-art Bluetooth chip that offers a strong wireless connection. You also get up to 10 hours of battery life on a full charge, so I think that should cover even the most hardcore workouts. Tuned for classic Klipsch sound Vlad also explained that the new Bluetooth technology helps Klipsch provide the audio performance they're known for. Basically, a stronger wireless connection equals better sound. It allows the 5mm drivers inside the T5 Sport earbuds to do their thing. They deliver that famous Paul W. Klipsch sound ? high on detail, low on distortion ? with nice helping of bass to fuel your workout. Soft oval ear tips for patented comfort For workout headphones especially, fit and comfort matter. So Klipsch includes their patented oval ear tips. Klipsch includes three sizes of these soft silicone earbud covers that slide in easily and comfortably. I find they avoid pressure points and create one of the best noise-isolating seals out there ? crucial for getting solid bass response. There is also a pair of Comply foam tips inside the box. These special tips conform to the shape of your ear canal to create a tight seal. Klipsch includes a set of "ear wings" to further stabilize the earbuds, and a cord cinch to adjust the connecting cable behind your head. Built and developed from years of research they didn't just stumble onto their oval ear tip design. V For this sport model, Klipsch gave the slim earpieces a unique, angled shape for a more secure fit. This keeps them from moving around during exercise and also helps isolate your music from outside noise.
